GAS OR VAPOR BURNER FOR HEATING.

SPECIFICATION forming part of Letters Patent No; 400,602, dated April 2, 1889.

Application filed November 7, 1887. Serial No. 254,463- (No model.)

York, have invented a new and useful 1m provelnent in Gas or Vapor Burners for Heating, of which the following is a specification. I

My invention is applicable to heating-burners, whether the material employed for fuel be gas or vapor generated from hydrocarbon liquid or petroleum-oil.

The invention consists in a combustion plate or burner in an apparatus for burning gas or hydrocarbon vapor, consisting of a disk composed of a ring or band and a fagot of parallel fine wires or pieces of metal, through the interstices of which the vapor or gas passes, and on the end surfaces of which ignition and combustion take place.

'In the accompanying drawings, Figure 1 is .a vertical section and partial elevation of a burner embodying my invention and adapted for the combustion of hydrocarbon liquid,

such as petroleum. Fig. 2 is a plan of such apparatus. Fig. 3 is a plan of the reducingring, which may be employed to cover a part of the combustion plate or burner and reduce the amount of flame which the burner produces. V

Similarletters of reference designate corresponding parts in all the figures.

A designates the combustion plate or burner, which extends across a mixing-chamber, B, having at the bottom an air-inlet nozzle or mouth, B. Above the combustion plate or burner A is arranged a heater, 0, with which engages, under control of a cook or valve, 0, a pipe, 0', leading from a reservoir or tank, 0 for petroleum or other hydrocarbon liquid, and from which extends a pipe, 0 having at the end a vapor-nozzle or outletropening, c, which is presented at the air-inlet B of the mixing-chamber B.

The combustion plate or burner A, which is fitted to and extends entirely across the chamber B, is composed of an annular ring or inclosing-band, a, formed of metal and filled in tightly with a fagot composed of parallel portions of metal wire, tubes, or pieces a. The combustion plate or burner thus constructed constitutes virtually a circular fo-' has a tendency to heat the gas passing upward through it, as hereinafter described, and thereby an economy of combustion is produced. The heater 0 is composed of a volute coil of pipe arranged approximately concentric with the circular foraminated or perforated combustion-plate A. Within this coil of pipe I generally arrange an inner core or center, which may be composed of wire or of a metal tube, and which simply serves to form an annular passage for oil or gas through the heater, and by forming such annular passage causes the oil or gas to pass in contact with a larger heating-surface. This oil or gas, which passes through the heater, or the gas alone if the heater C be connected directly with a gas-pipe, is heated or vaporized by the heat from the combustion plate or burner A, and finally issues from the gas-outlet c and enters the combustion-chamber B, together- With the air which may be induced to flow in therewith through the inlet B. In the combustionchamber B the vapor and air become intimately mingled, and, finally passing through the combustion plate or burner A, they areburned and heat is produced.

In some cases it may not be necessary to employ the entire area of the combustion plate or burner A, and I therefore employ-a ring, D, which is ofa size to fit over the plate or burner A near the periphery of the chamber B and to reduce considerably the exposed surface of the combustion plate or burner. The reducing-ring D has in it a notch, d, which may lie over the radial inlet-pipe, as shown in Fig. 1, and through the inlet-pipe C hydrocarbon liquids or gas are supplied to the heater 0, and are by said heater superheated or brought to a high degree of heat.

What I claim as my invention, and desire to secure by Letters Patent, 'is

In an apparatus for burning gas or hydrocarbon vapor, the combustion plate or burner herein described, consisting of a disk com posed of a ring or band and a fagot of parallel fine wires or pieces of metal, through the interstices of which the vapor or gas passes, and on the end surfaces of which ignition takes place, substantially as herein set forth OTTO ROTTON.
